@robotiko yes linux for me. Might try at some point to get it up when i get my jtag from aliexpress

I found another cause for reboot: call stack overflow. I located the offending routing which had a local variable defined with 2048 bytes. I am updating it with malloc but takes some time as there are numerous exit points for that decoder and i need to wrap calls to free for each

PNG decoding was guilty

I will look for other large declarations in the code and try to commit my work to the original library after i am done; this will make it easy to pull future updates from the original repo (stb libraries)

@sle118 : There is no yield() function in Sming.In NONOS you should reset wdt within your processing.Current experience with RTOS is that it will not suffer wdt resets. But needs to be tested more to be fully sure.
